Bennett will play Slade Wilson, otherwise known as the man who eventually becomes Deathstroke. The DC Comics villain has already appeared on The CW series during a flashback, but he was masked and portrayed by a different actor.

Bennett is a New Zealand actor best known for playing the slave-turned-rebel Crixus on Spartacus. He'll also appear in two of the upcoming installments of Peter Jackson's big-screen adaptations of The Hobbit.
